Phenomenological MSSM in light of new 13 TeV LHC data

Abstract

We present the first analysis of the p19MSSM with neutralino dark matter, in light of 13 TeV LHC data with an integrated luminosity of ~14/fb. We recast twelve experimental analyses performed by the ATLAS collaboration and derive exclusion bounds on the parameter space of the model. We find that 25% of the model points can be excluded at 95% C.L. by a combination of the implemented searches. The spectrum allowed after the 13 TeV results are taken into account presents stops heavier than at least 400 GeV, gluinos heavier than at least 790 GeV, and squarks of the first and second generation heavier than at least 440 GeV.

21 pages, 9 figures. Analysis extended to incorporate the p19MSSM models that satisfy only the upper bound on the relic density of dark matter. Version published in the European Physical Journal C
